Abstract: A device for engaging and holding a sole of a ski boot, which device includes a sole holder which is adjustable in a vertical direction relative to the ski by means of an adjusting screw and is connected to a ski binding part which is associated therewith. The adjusting screw is secured to the ski binding part and is prevented from lifting off in a vertical direction from the ski while at the same time is swivelably supported on a base plate. The sole holder can, during an automatic release operation (safety release) be swung slightly upwardly from the ski on a side of the ski facing the release side. The sole holder performs a normal pivotal movement with respect to the longitudinal axis of the ski or a combined pivotal and swivel movement about differing pivot axes. Structure is provided for urging the sole holder into a normal ski boot holding position.

Abstract: A safety binding for skiing boots, including a toe holder, a heel holder, a spring-loaded locking member, which is mounted to be displaceable in the direction of its longitudinal axis against a spring force and has a convexly curved head which cooperates with a concavely curved surface of a keeper. The keeper is connected to the heel holder and is pivotally movable relative to the longitudinal axis of the locking member, wherein the concavely curved surface of the keeper has different radii of curvature in a vertical plane and in a horizontal plane and the heel holder is pivoted on a horizontal axis and on a vertical axis. The horizontal and vertical pivotal axes of the heel holder cross each other and are spaced different distances from the forward edge of the heel holder exceeding the smallest distance from the point of contact between the head of the locking member and the keeper to the forward edge, which faces the toe holder or the boot.

Abstract: This invention relates to a safety binding comprising a soleplate. The usual bindings may release the boot in response to a deflection of the ski caused by large waves. It is an object of the present invention to provide a binding which has a soleplate and which can store a larger energy and will not undesirably release the boot in response to a resilient deflection of the ski. Besides, the binding according to the invention provides for favorable kinematics as regards the movements which result in the release of a boot by a safety binding. For this purpose the invention provides a spring-biased heel holder and a soleplate, which is mounted to be displaceable in the longitudinal direction of the soleplate and is connected to the heel holder by a universal joint and which near that end which is remote from the heel holder is pivoted on an axis which is transverse to the soleplate.

Abstract: This invention relates to a safety ski-binding of the kind comprising a heel binding and a front binding including sole-clamps to hold down the toe portion of the sole of a ski-boot. According to the invention, the sole-clamps are mounted to tilt about a pivot shaft which is arranged to extend transversely to the longitudinal direction of the ski, when mounted, below the plane of the bottom of the sole of the ski-boot, and they are capable of pivoting to a position in which they point forwards towards the point of the ski and are situated below the plane of the bottom of the sole of the boot. Moreover, each of the sole clamps has an abutment which retains the boot sole in the longitudinal direction of the ski, and a lug which retains the sole of the boot in a direction perpendicular to the plane of the sole, and furthermore the sole clamps are connected to a locking arrangement which permits them to perform their pivoting movement when a pressure threshold is exceeded.

Abstract: A safety binding adapted to be mounted on a ski.This binding comprises a one-piece jaw in which engages and is maintained one end of the sole of a ski boot, this jaw being urged under the action of a resilient device against two support lines and being characterized in that the support lines, viewed along the axis of the ski, converge towards a point located above the ski.

Abstract: A ski binding having a retaining device which secures a skier's boot to a ski. The retaining device releases the boot when the lateral, longitudinal, and/or upward forces acting between the ski and the boot reach a predetermined level. The retaining device includes means which function to generate a force which is equal to and opposite to the force generated by the acceleration of the boot mass in the lateral and/or vertical directions so as to cancel out the internal forces resulting from such accelerations and thereby eliminate the premature release of the ski bindings.

Abstract: The safety binding comprises a vertical pivot integral with a base mounted to the ski, a binding rotating upon the pivot and carrying means for retaining the boot, a locking system ensuring that the boot is maintained in a specific position upon the ski, and a compensating mechanism acting upon the locking system to cause a lateral retention force applied to the boot to vary inversely to a vertical retention force. The compensating mechanism includes a first part mounted to pivot about an axis at right angles to the longitudinal axis of the ski, and a second part mounted in the binding and movable relative to the first part; this second part cooperate, through a system of ramps, with the boot-retaining means to oppose the lifting of the boot.

Abstract: A safety ski binding comprises a movable plate for supporting a ski boot, and is mounted for pivotal movement in a plane parallel to the ski; toe-end and heel-end devices are adapted to retain the plate under normal skiing conditions against upward and lateral movements; the toe-end device comprises co-acting inclined and curved surfaces, and the heel-end device comprises a tilting arm pivotally mounted to a transverse pivot pin carried by a pintle mounted in turn for rotation about its axis perpendicular to the ski surface; spring-loaded members normally urge the tilting arm to its normal skiing, boot-retaining position; the plate is adapted to be released in all directions when subjected to excessive stress.

Abstract: A safety ski binding comprising a detachable, pivotally-mounted plate for clamping the ski boot at the toe and heel ends thereof, and toe-end and heel-end devices for releasably holding said plate to the ski. The heel-end device essentially comprises a lock-bolt pivotally mounted to a case pivoting in turn about a pivot member rigid with, and perpendicular to, the top ski surface. The pivot axis of this lock bolt is perpendicular to said pivot member and parallel to the top ski surface, and extends across the longitudinal axis of the ski. This arrangement further comprises resilient means enclosed in said case and adapted to retain both said lock bolt in relation to said pivoting case and said pivoting case in relation to its pivot member in their normal operative position.

Abstract: Safety ski bindings include a boot retaining clip for engaging a ski boot at the heel and/or toe thereof. A toggle linkage system is operably connected to the boot retaining clip and is movable between a locked position for forcing the retaining clip against the boot to retain the boot on the ski, and an unlocked position for disengaging the retaining clip from the boot to permit the ski boot to separate from the ski. An actuated member is movable to unlock the linkage system to permit the linkage system to move into its unlocked position for releasing the retaining clip from the ski boot when the ski binding is displaced a certain distance relative to the ski in either one or both of two directions which are perpendicular to each other. Preloaded biasing means resist the displacement of the ski binding relative to the ski in one of the two directions, and a different preloaded biasing means resists the displacement of the binding relative to the ski in the other direction.

Abstract: Disclosed is a ski binding release assembly for releasably clamping the toe or heel of a boot with a ski, the extent of pressure necessary to effect lateral release of the boot and ski provided by a plate and coupled shaft rotatably mounted with the assembly housing and rod and spring assembly for adjusting pressure against the shaft; the extent of pressure necessary to effect upward release of the boot and ski provided by adjustable spring pressure against rollers resiliently urged into engagement with a pivotally mounted clamp support body. Slidable coupling between the release assembly housing and the mounting plate affixed to the ski enables limited longitudinal movement between the ski and release assembly.

Abstract: A safety ski binding is designed so that the ski boot resting on a plate joined permanently but pivotally to the ski is secured only by a single holding element, which is designed as a heel element. This holding element is joined to the ski so that it can be swivelled toward all sides, and has a release mechanism which releases the ski boot both in case of forward falls and in case of torsional falls. The release characteristic can be differently adjusted in different directions in accordance with the tensile and torsional stresses to which the leg is subjected.
